Best Cheapo Ebay DIY Amp Kit?

So I've decided that I want to build a headphone amp just for fun. However, this is my first time attempting this as well as my first time soldering so I don't want to spend much money on it given the relatively high likelihood of me completely messing it up. So I was wondering what you all though about the cheap headphone amp kits on ebay?

Are they at all worth the time and money to build or just total garbage?
